Thank you both of you very much indeed,
Could you please understand me? I think that my questions are related to XenForo pre-sales . If you kindly have a look again to my previous post, you will find that I've been asking about:
First: Each Website has domain name, and a logo. Thus, I am really expecting that if I own an existing website, for instance 'SouthArabia.com', thus, So far, my website has an icon, although the XenForon is not yet installed), and then if I want to integrate a forum, I simply go to buy XenForo for $140 plus VAT and then I can get support. Thus, my website 'SouthArabia.com' will have a forum powered by XenForo. I will end up with a website having a forum.
Second: could you kindly enlighten me a little bit, since I really noticed that each website on the internet has an icon shown in front of its domain name (especially, this icon is shown once URL of the website is saved in Programs Storing the Logins of Websites, such as Norton Identity Safe). Thus, I think that domain name of website created at web builder service, itself, has the icon, and XenForo software does nothing with icon as long as the Xenforo software will be installed on the web-hosting space. I.e. website will have domain name, and the icon. However, Xenforo software will be only installed in the web-hosting space to add a forum. I can run my website hosted on web-hosting service without needing to have a XenForo installed. If I need to extned my website to include a forum, then I will only need to purchase and install 'XenForo software.
